BD & Cervix

During BD last night, my DH was hitting my cervix, but only in a certain position. I really couldn't tell if it hurt, felt good or felt awkward. He moved a bit and then it started to hurt slightly, but also in my stomach! Imma bout 7 dpo approx. And all day today I've had a weird feeling, not really a cramp, may be more like a sensation or pulling. No bleeding or anything or pain. This ever happen to anyone?
